■Biographical Memoir of the lale Henry KM. 7 



distant from the city of Groningen, Avhere they were kindly re- 

 ceived by Albers, Treviranus and IMertens. In the museum of 

 this city, there was a remarkably good zoological collection, and 

 Aibers''s private cabinet was well stored^ particularly in compa- 

 rative anatomy. Kiihl took notes of every thing that he saw. 

 From Bremen they went to Brunswick by Cella, and there they 

 visited the Duke's collection, which is very rich in preparations 

 of amphibia, both anatomical and osteological, while it is at the 

 same time well supplied with birds. From thence they set out 

 without delay for Berlin, where they arrived on the 2d or 3d 

 of July. 



Immediately after their arrival, they visited Lichtenstein, 

 whom, having known two years before, they found a very ac- 

 complished man, as well as a very learned zoologist. " He 

 treated us," says Kiihl, in a letter to Swinderen, " as if we had 

 been his own children ; and whenever we visited the Royal Mu- 

 seum, or Lichtenstein's own library, we commonly supped at 

 his house.'''' 



In this manner they spent some weeks in Berlin, applying to 

 their studies with the utmost diligence ; and the last days of 

 their stay were further improved to them by the arrival of the 

 celebrated Temminck. From thence they proceeded to Halle, 

 where they met Professor Nitzsch, and other naturalists ; to 

 Leipsig, Dresden, and into German Switzerland, and, lastly, to 

 Jena, being every where received in a friendly manner. 



Kiihl also paid a visit to Naumann upon this journey, and 

 the respect which he had before entertained for this celebrated 

 ornithologist, was by no means diminished by his personal ac- 

 quaintance with him. As the time allotted for their excursion 

 was now drawing to an end, they spent the remainder of the 

 vacation in the house of Kiihrs father, making a short journey 

 to Heidelberg, where Tiedemann gave them very useful advice, 

 with regard to the manner in which comparative anatomy should 

 be treated. 



From thence they returned to Groningen, on the 21st of Sep- 

 tember. In this year Swinderen read his fuller lectures on the 

 cold-blooded animals, and the three great divisions of the inver- 

 tebrata, in which he very ingenuously confesses that he was not 

 less studiously assisted by Kiihl in respect to mental than
